CARTRIDGE SHELL AND rocnss or armi senin To a'ZZ 'whom t concern.' y Be A it known 4 that I, GEORGE W. SGHAUERTE, a citizen of the United States, and residing at Alton, county of Madison, State of Illinois, have invented the new and useful Improvement in Cartridge Shells and Processes of Making the Same, of which the following isua specication. y This invention relates to cartridge shells, and more particularlyto those designed for use in shot guns. l f

A shot gun shell usually comprises a tube, usually formed of paper or similar 'material, a base which isv usually formed of metal, such as brass, and a base wadfalso usually formed of paper, the base and the base wad being provided withv a socket for receiving a battery cup. It is .necessary that the elements of the cartridge shell be firmly interlocked to form a unitary struc.- ture.

One of the objects of this invention, therefore, is to provide a cartridge shell in which the base and the base -wad will be securely interlocked in a simple and e'ec- Another object of this invention is to provide a'cartridge shell embodying a tube of paper or the likerin which the base wad will not only be interlocked with .the base will be interlocked with the base.

Another object of this invention is to provide avnovel process of assembling the elements of the -cartridge shell,'.-whereby these elements are interlock/ed in a simple and effective manner to lform a unitary structure.

N Further objectswill appear fromithe detail description taken in connection with the accompanying drawing, in which:

Figure 1 is a detail section, somewhat enlarged, of the baselend ofthe shell showing one of the steps in the'interlocking of the elements of the shell;

Figure 2 is a section showing the process of securinginterlocking ofthe elements;

Figure 3 is a view similar to Figure 1` but in perspective showing -the elements of the shell interloclied; and 'I Figures 45, 6 and 7' are sectional views showing various embodiments of this invention. y

Referring to the accompanying drawing and more particularly to Figures 1 and 3,

Application led October 6, 1923. Serial No. 666,i)16. .v

the. elements of the shell comprise a tube 1, which is usually formed of paper, a basewad 2, also usually formed of paper, and a base 3 which is drawnv to shape and is usually formed of brass.- The base and the base wad are apertured to form a socket 'which is arranged to receive a battery cup 4 of any suitable or usual construction. also has the usual peripheral flange 5.

In accordance with this invention the base flange 5 is preliminarily formed only .partially as shown in Figure 1 so as to permit ready insertion of the tube l. The cencentral flange which is serrated to form a series of prongs Gand the ends of these prongs are turned to pro'ect outwardly as shown at 7 The'base-wa furthermore has its aperture 8 large enough so as to slip freely (over the battery cup and-the out- The base yter of this base is also formed to provide a wardly-projecting prongs 7 which, as heretofore described, provide an anchor. After the elements of the shell have been assembled, as shown in Figure 1, they are secured together in interlocking relation by a process of condensing the base-wad and crimping the base flange 5 by upsetting the partially formed" peripheral flange 5. These operations can be performed by any suitable mechanism. Thus, as shown in Figure 2, the'assembled elements may be placed inside of a tubular support 9 having an annular recess 10 to receive the flange 5, while insertible into the tubev is a plunger 12 formed as shown and cooperating with a second plunger 11. In operation the `plunger 11 is movedN towards the support wad. Furthermore the cooperation of the 100 plunger 11 with the plunger 120 not only causes the end of the tube tovbe forced into the annular recess formed bylthe inoomplete flan le 5, butthe-end of the base-wad of the tube; furthermore the pressing of the base against the shoulder 10 will complete the upsetting ofthe flange 5 an'd thus firmly crimp the base on the tube.-l The result is, therefore, that the elements of the tube 110 itself wi be orced vout against the end the base-wad to close on the cup and -into L on the reinforce 12.

will become firmly interlocked as shown in Figure 3 with the base-wad interlocked' with the base and With the tube, while the tube is interlocked with the base. In the embodiment shown in Figure 4 -a` reinforce 12 is provided for the base 3 and this reinforce has a central flange serrated to forni prongs provided with outturnedY ends 7 0- thereby forming anchors similar to 6 and7 and lying against the battery cup 4. vThisl reinforce is usually of steel and when used, -the flange on the base need only be short as ,shown in Figure 4, while the anchor.- on the reinforce forms ineifect a continua- 1 tion of this flange. .In the assembling of .the elements shown in the embodimentV of Figure 4 it will be understood that both the base and the'reinforce have their eripheral flanges 51 and 5 0 only partially ormed. ina manner similar to that shown in Figure 1, and that in the interlocking ofthe parts the operation will be substantially as shown in -F1 re 4, namely the condensation of interlocking engagement. with the anchor. on the reinforce, while the flanges 5 and 50 are upset so as to secure interlocking of the tube, reinforcefand base. v i

In the embodiment shown in Figure 5, anchors are formed both on the base 3. and

the process of interlocking the elements of the shell will be readily understood from what has been described with reference to :Figuresl to 4 inclusive. v In the embodiment shownin Figure 6 the battery cup itself vhas the anchor formed thereon by upsetting its inner 'end to form la Vperipheral flange 71 which is arranged \to-interlock"iwith the base-wad, for it will be readil understood that u on condensa'- tion of t e'wad the same is orced against the battery cup and underneath-the flange thereon so as. to elfectively interlock the parts, it being understood that the battery. cup itself is provided with a flange 13 which is retainedby inwardly the base shown at 14.

f In the embodiment shown in Figure 7 the battery cup -4. vhas struck up therefrom prongs 72 over whichA the base-wad 2 is' arranged to be slipped to be subsequently` condensed so as to lmbed vthese prongs in 7 the base-wad. In this embodiment also the battery cup is retained by the engagement of the ange 13 thereon with theflange 14 on the base. j

It will, therefore, ber seen that the inven-l tion accomplishes its objects. A 'cartridger shell is Aprovided in .which the elements thereof are lsecured in firm interlocking engagement in a simple and effective manner.I

The arrangement is suchthat the tube and the base-Wad can be readily slipped into the base and over the battery cup and thel outhe construction and a socketformed by l'langing wardly projecting anchors; then by a simple i operation the Wad is condensed on the bat7 tery cup and the anchor to interlock the. same, while the base-wad, tube and base are firmlyv interlocked'.

It is obvious that various changes maybemade in details without departing from the spirit of this inventiongit is, therefore, to

be understood that this invention is not to be limited to the specilic details shown and described.` c
